Please help. I cant figure out the first step, where to begin on these problems.

4 * ( -9 ) - -25 =

r - 60 = -38

10 - ( -78 )

42 = 7t - 42

Thanks.

4 * ( -9 ) - -25 =

36 - 25 = 11

So where exactly did the 36 come from?

was that from 4 * 9?

That must be it. - Feb 10th 2007, 04:43 PMAfterShock
